* CTR: control character specific to the charset.

* RET: carriage/return.
|
|
* SYM: symbol (punctuation) that does not belong to word.

* NUM: 0 - 9.

|
|
* Other characters are ordered by probabilities

* Orders are generic to a language. So the codepoint with order X in
|
|
* CHARSET1 maps to the same character as the codepoint with the same
|
|
* order X in CHARSET2 for the same language.
|
|
* As such, it is possible to get missing order. For instance the
|
|
* ligature of 'o' and 'e' exists in ISO-8859-15 but not in ISO-8859-1
|
|
* even though they are both used for French. Same for the euro sign.
